The thrice-married billionaire businessman, who sometimes brings a copy of his boyhood bible and a photo from his confirmation to events to bolster his Christian credentials, worked to appeal to the crowd of more than 11,000 students and local residents by quoting from the scripture.

The visit comes as Trump seeks to bolster support among the evangelical Christians who form a significant voting bloc in Iowa — first among the early voting states in the primaries — where Trump is currently running head-to-head against Texas Sen. Ted Cruz. Cruz launched his campaign at the school.

The campus has become a popular stop for presidential contenders, welcoming candidates from both parties, including Democratic hopeful Bernie Sanders.

While Trump is running against several candidates who have deep ties to Christian votes, he was given a rousing introduction by the school's president, Jerry Falwell, Jr., who called Trump a "breath of fresh air" and compared his blunt style, not only to his father's, but to that of Martin Luther King, Jr. and Jesus Christ. All spoke the truth, no matter how unpopular, Falwel said.

Falwell also made the case that presidential candidates should not be judged on their religiosity, noting that his father was criticized for supporting Republican Ronald Reagan, a divorced Hollywood actor over Jimmy Carter, a southern Baptist Sunday school teacher.
